Chemical Structure
Description
The occurrence of 2-((1,1-Dioxidotetrahydrothiophen-3-yl)(methyl)amino)-2-oxoethyl 2-(thiophen-2-yl)quinoline-4-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-((1,1-Dioxidotetrahydrothiophen-3-yl)(methyl)amino)-2-oxoethyl 2-(thiophen-2-yl)quinoline-4-carboxylate (CAS 868270-08-0) is a high-purity analytical reference standard with the molecular formula C21H20N2O5S2 and a molecular weight of 444.52 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((1,1-Dioxidotetrahydrothiophen-3-yl)(methyl)amino)-2-oxoethyl 2-(thiophen-2-yl)quinoline-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
